Test ID:1.3.6.1.4.1.25623.1.0.50775
Category:Mandrake Local Security Checks
Title:Mandrake Security Advisory MDKSA-2003:118 (XFree86)
Summary:NOSUMMARY
Description:Description:

The remote host is missing an update to XFree86
announced via advisory MDKSA-2003:118.

A vulnerability was discovered in the XDM display manager that ships
with XFree86. XDM does not check for successful completion of the
pam_setcred() call and in the case of error conditions in the
installed PAM modules, XDM may grant local root access to any user
with valid login credentials. It has been reported that a certain
configuration of the MIT pam_krb5 module can result in a failing
pam_setcred() call which leaves the session alive and would provide
root access to any regular user. It is also possible that this
vulnerability can likewise be exploited with other PAM modules in a
similar manner.

A backported patch from XFree86 4.3 that corrects this vulnerability
has been applied to these updated packages.

Affected versions: 9.0, 9.1, 9.2, Corporate Server 2.1

Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
